摘要
通过对喷射工艺以及机制砂和钢纤维喷射混凝土特点的分析,直接采用增加水泥用量和保持机制砂中石粉含量和合理的喷射工艺,设计机制砂钢纤维喷射混凝土,在施工中能取得好的效果。
Based on the analysis of spray technology and characteristics of machine-processed sands and steel fiber sprayed concrete,steel fiber sprayed concrete with machine-processed sands is designed by directly increase the cement content, keeping the stone powder content of machine-processed sands and adopting reasonable spray technology and a good result is also obtained in construction.
